It's no secret that a tight ponytail can lead to headaches - pulling the hair back so tightly strains the scalp tissue. In some cases, ponytails can increase the likelihood of developing tension alopecia.

Whether you suffer from these symptoms likely depends on your scalp sensitivity.

"We know some people have more sensitive nerve endings in their scalp than other people. And if those folks are wearing a tight hairstyle and a ponytail, that's going to induce an achiness after the hairstyle is released," Dr. Wade Cooper, an associate professor in neurology at the University of Michigan, told Fox 2.

"That's going to signal to us that their nerves are triggering underlying brain sensitivity that we see more commonly in people with migraines or other pain syndromes."

If you find yourself suffering from an unpleasant headache while wearing a ponytail, let your hair down and the pain may ease. And it's best not to sleep with your hair in a tight ponytail to decrease the likelihood of neck strain.
